Capture image from GPU? (OpenCV, CUDA)

I want to know, is it possible to read a video (capture an image) directly from the GPU with Open CV, without capture the image with CPU and then upload it to the GPU?

I found the funtion : cv::cuda::VideoReader. But i couldn't understand the difference between cv :: cuda :: VideoReader and cv :: VideoCapture
